If your computer has more than one processor core, use
<code>make -jN</code> instead of <code>make</code> in the last line
above, where <code>N</code> is the number of processors you have.

Trilinos sometimes searches for other libraries but can't find
them if they are not in the usual directories or have other

+ <h5>Using external direct solvers</h5>

+ <p>
+ Trilinos (via its Amesos package) can interface with a number of direct
+ solvers (see, for example,
+ <a href="http://trilinos.org/docs/r11.8/packages/amesos/doc/html/index.html"
+ target="_top">this page for Trilinos 11.8</a>). Most of them are external
+ packages to Trilinos and you will need to tell Trilinos configuration
+ scripts that you want to use them, for example via the
+ <code>TrilinosWrappers::SolverDirect</code> class. This can be tricky,
+ but adding defines similar to the following to the cmake command line
+ will achieve the goal:

+ -D TPL_ENABLE_SuperLU:BOOL=ON \
+ -D TPL_ENABLE_SuperLUDist:BOOL=ON \

+ -D SuperLUDist_INCLUDE_DIRS:FILEPATH="/path/to/SuperLU_DIST_3.2/SRC" \
+-D TPL_SuperLUDist_LIBRARIES:FILEPATH="/path/to/SuperLU_DIST_3.2/lib/libsuperlu_dist.a" \
